window screens. i s

Theobject of the present invention is to improve the construction, of window screens, and to provide a simple and inexpensive window screen comprising a pair of upper and lower screen members or screens, adapted to be readily introduced into and removed from a window frame, and capable of being arranged with both the upper and lower screens or screen members at either the top or bottom of the window, or with one at the top and the other at the bottom to permit the heated air to escape at the top and the fresh air to enter at the bottom.

A further object of the invention is to provide a window screen, equipped with a device'adapted to secure the screen members in slidable engagement with the window frame, and capable also of retaining the screen members at any intermediate position between the top and bottom of the window frame.

With these and other objects in View, the

invention consists 1n the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

is a detail perspective view, illustrating the construction of one of the joints of the window screen frame.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In theaccompanying drawings in which is illustrated the preferred embodiment of the invention, the window screen comprises in its construction upper and lower screen members or screens 1 and 2, each preferably provided with two thicknesses of screen material 3 and 4, the screen material 3. having the wires of mesh arranged vertically and horizontally, while in the other screen material 4, the wires are arranged diagonally.

This arrangement effectually excludes gnats and othersmall insects. The screen material may be secured to the frames of the upper and lower screens by any suitable means, and the bars of the screen frames may be secured together at their ends in any preferred manner. Each .of the upper and lower screen members or screens is provided at the left hand side with a groove 5 and at the right hand side with a rabbet 6, and is retained in slidable engagement with vertical strips 7 and 8 of a window frame 9 by means of a pivoted catch 10.

The pivoted catch is constructed of a single piece ofspring metal doubled at the end 11 to form two thicknesses and provided" through the doubled portion with a perforation through which passes a pin 12, or-other suitable fastening device, which pivots the catch in a recess 13 of the screen member or screen. Therecess 13 is narrow and oblong,

and the catch is adapted to be swung into and out of the same to engage it with and disengage it from the strip 8, and 1t is provided at its free end with a projecting operating lip 14, and it has a resilient wing 15. The lip 14 extends outwardly and it Is received within a notch 16 of the screen frame,

- of one of the sashes 22 of the window frame,

I when the catch is moved inwardly to perend thereof and bent inwardly across the same and terminating adjacent to the lip 14. The resil ent wing, which, when not compressed, 1s arranged at an acute angle to ,the body portion of the catch, is adapted to be compressed in'the recess 13 and it also maintains the catch in frictional engagement with the strip 8 to retain the catch in its engaging position and also for holding the screen at the desired vertical adjustment.

The screen frame of each screen or screen member is recessed or cut away adjacent to the notch 16 to enable the lip 14: to be readily operated by the thumb, and the sides of the screen are also provided at their inner edges with opposite recesses 17 to enable the screen to be readily gripped in replacing it in and removing it from thewindowframe.

The upper screen 1 is provided inits upper edge with a groove 18 to receive a top strip 19 of the window frame, and the lower edge of the upper screen 1 is also provided with a groove 20in which extends a metallic strip 21 of the lower screen 2 when the screens 1 and 2 are fitted together either at the upper portion of the window, as shown in Fig. 1, or at thebottom thereof. The combined dimensions of the upper and lower screens are equal to the dimensions and this enables both screens to be arranged at either end of the window frame when the sashes are moved 'in the opposite end, and the screens may also be arranged above and below the sashes, as illustrated in Fig. 2, to afford free ventilation. The upper screen 1 is provided at the top with spaced projecting studs 23, and the lower screen 2 is provided with a central stud 24. Each of the studs consists of an inner shank or portion, which is secured in a socket or recess of the screen frame on which it is mounted, and it projects upwardly therefrom, the projecting portion being provided'with diametrical slots or kerfs 25 forming resilient clamping portions. The pro ecting resilient clamping portions of the upper screen are adapted to frictionally engage spaced sockets 26 in the top of the window frame,

and the central stud 24 of the lower screenis adapted to engage a similar socket 27 in the lower bar of the frame of the upper screen.' Each of the sockets is lined at its lower portion with a metallic thimble 28, having an outwardly extending flange 29 at the lower end. The resilient studs extend into the sockets and project beyond the up;

per ends of the thimbles. The resilient portions of. the studs are compressed in inserting the same into the sockets, and they expand beyond the upper ends of the thimbles, and there is suflicient frictional engagement to maintain the sashes in an elevated position, and as the clamping action at the top of the upper screen is twice that at the top of the lower screen, the latter is adapted to be pulled out of engagement with the upper screen without disconnecting the said upper screen from the top of the window frame.

The bars of the frames of the screens 1 and 2 are preferably connected by dovetailed the other having a dovetailed rib 31 to slid-v ably engage with the groove.

What is claimed is:

1. In combination with a window frame.

and its sashes, an upper sereen and a lower screen mounted in the frame, said screens having a combined area equal to one of the sashes, a frictional connection between the upper screen and the window frame to maintain the said screen at the top of the said frame, and a frictional connection between the meeting edges of the lower screen and the upper screen to permit both screens to occupy the top of the frame,..the frictional connection. between the two screens being weaker than the frictional connection between the upper screen and the frame, whereby the lower screen may be separated from the upper screen and lowered without disconnecting the upper screen from the said frame. a

2. The combination with a. window frame provided at opposite sides with strips, of a screen provided at one side with a groove to slidably engage one of the strips and having a rabbet at its opposite side to receive the other strip, said screen being also provided at its rabbeted side with a recess, and a catch pivoted in the said recess and adapted to be swung inwardly and outwardly to engage it with and disengage it from the adjacent strip of the window frame and .provided with a resilient wing compressible against the 'catch to permit the latter to be moved into the recess and maintaining the catch in frictional engagement with the window frame when the catch is swung out of the recess. 3. The combination with a window frame provided at the top with spaced sockets, of an upper screen having a. single socket at the bottom and provided at the top with projecting resilient studs arranged to ex-' tend into the sockets of the window frame and frictionally engaging the walls of the same, 'and a lower screen provided at the top with a single resilient stud arranged to frictionally engage with the socket at the bottom of the upper screen, said screens being s1id able in e window frame and the lower screen being ada ted to be pulled out of engagement with t e upper screen without disengaging the same from the window frame.

4. The combination with a window frame provided at the top with s aced sockets, of upper and lower screens sli able in the window frame, the upper screen being provided at the bottom with a single socket, metallic thimbles lining the lower portions ofv the said sockets, spaced resilient studs projectin from the upper screen, and a single resillent stud extending from the lower screen, said studs being arranged to enter the said sockets and to extend beyond the metallic thimbles thereof.

In testimony, that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
